Comcast Offers to Turn Customers’ Wi-Fi Routers Into Motion Detectors
August 19th, 2026Via: Engadget:
Comcast has unveiled a new home security platform it’s calling Xfinity Shield. The company says this combines home, family and cybersecurity protection in a single app and it puts Wi-Fi at the center.
It’s offering a service called Wi-Fi Shield to Xfinity Internet users at no extra cost. This includes a few features, including one called Wi-Fi Motion. Comcast says that a typical Xfinity customer has 36 devices connected to Wi-Fi. This particular feature, which is opt-in, can detect movement inside the home by picking up on changes in the radio frequency signal between the Xfinity Gateway and a connected device. If the system detects any unexpected changes, you can receive immediate notification via the Xfinity app.
Comcast says Wi-Fi Motion, which uses Xfinity Gateway intelligence, “provides an added layer of awareness without recording video, capturing images or identifying individuals.” This kind of technology isn’t exactly new, but it’s interesting to see a notable internet provider integrate it into a home security platform.
